Coffee drinkers have less fat, more muscle, and surprising hormone differences - Science Daily

“Recent research highlighted in Science Daily finds that regular coffee consumers in the United States tend to have lower body fat percentages, higher lean muscle mass, and distinct hormone profiles—including elevated testosterone in men and altered estrogen levels in women. The study, which analyzed a large, nationally representative cohort, suggests that caffeine‑driven metabolic pathways may enhance fat oxidation and protein synthesis, while also influencing endocrine function. These findings arrive as coffee sales in the U.S. exceed $100 billion annually, positioning the beverage as a potential low‑cost adjunct to weight‑management and fitness regimens. Expert Analysis: The hormonal shifts observed could drive a new wave of functional coffee products marketed toward performance‑focused consumers, prompting manufacturers to invest in scientifically backed formulations. If clinicians begin to endorse moderate coffee intake for body‑composition benefits, the U.S. health‑and‑wellness market may see a measurable uptick in demand for premium, specialty brews.”
